Splitting a start and end date by interval in PHP [duplicate]

Question

This question already has an answer here:

• I have 2 dates in PHP, how can I run a foreach loop to go through all of those days? 8 answers

Is there any function to split a start and end date into chuncks of $interval days (or months)? For example:

$interval = new DateInterval('P10D');
$start    = new DateTime('2012-01-10');
$end      = new DateTime('2012-02-16');

$chunks = splitOnInterval($start, $end, $interval);

// Now chunks should contain
//$chunks[0] = '2012-01-10'
//$chunks[1] = '2012-01-20'
//$chunks[2] = '2012-01-30'
//$chunks[3] = '2012-02-09'
//$chunks[3] = '2012-02-16'

I think DatePeriod can help, but i didn't find any way on how i can use it.

Answer 1

Check this article on how to iterate over valid calender days.

In php its something like,

$start = strtotime('2012-01-10');
$end1 = strtotime('2012-02-16');
$interval   = 10*24*60*60; // 10 days equivalent seconds.
$chunks = array();
for($time=$start; $time<=$end1; $time+=$interval){
    $chunks[] = date('Y-m-d', $time);
}

Answer 2

Here is an example to iterate over days, over month is working accordingly with other interval

<?php

$begin = new DateTime( '2012-11-01' );
$end = new DateTime( '2012-11-11' );
$end = $end->modify( '+1 day' );

$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);

foreach($daterange as $date){
echo $date->format("Y-m-d") . "<br>";
}
?>
